Development and Programming of Low Power Cluster
 Hradecký, Michal ; Nikl, Vojtěch (referee) ; Jaroš, Jiří (advisor)
This thesis deals with the building and programming of a low power cluster composed of Hardkernel Odroid XU4 kits based on ARM Cortex A15 and Cortex A7 chips. The goal was to design a simple cluster composed of multiple kits and run a set of benchmarks to analyze performance and power consumption. The test set consisted of HPL and Stream benchmarks and various tests for the MPI interface. The overall performance of the cluster composed of four kits in HPL benchmark was measured 23~GFLOP/s in double-precision. During this test, the cluster showed power efficiency about 0.58~GFLOP/W. The work also describes the installation of PBS Torque scheduler and HPC software build and installation framework EasyBuild on 32-bit ARM platform. The comparison with Anselm supercomputer showed that Odroid cluster is as effiecient as large supercomputer but with slightly higher price.
